Answer:
x+y=8
Step-by-step explanation:
2(3x+y=20)
6x+2y=40
2x-2y=8
8x=48
x=6
18+y=20
y=2
Answer:
Step-by-step explanation:
Since all the answers are 100s I assume the sizes are 10, 10 and 20.
This would mean there are 2 sides of 10x10 and 4 of 10x20
The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800
Answer:
x=11
m<a=80º
m<b=80º
Step-by-step explanation:
They are congruent so
8x-8=5x+25
8x=5x+33
3x=33
x=11
Dilation because the sides will not be the same size as the original
Answer:
75 degrees
Step-by-step explanation:
360/60=6 degrees per minute on a clock face
minute hand, from 12 o'clock position is 30 minutes so 30x6=180 degrees
hour hand, from 12 o'clock position is 17.5 minutes so 17.5x6=105 degrees
180-105=75 degrees
